Method for enriching zinc of wheat grains through combined spraying of zinc and pesticides

Abstract

The invention discloses a method for enriching zinc of wheat grains through combined spraying of the zinc and pesticides. According to the method, winter wheat is used as a research object, a mixed solution of the zinc, the pesticides and biological stimulants is sprayed 7 days after flowering, the zinc enrichment effect of the wheat grains after the combined spraying of the zinc, the pesticides and the biological stimulants is studied, and a certain theoretical basis is provided for practical realization of an efficient grain zinc enrichment technology. The method has the advantages that thecombined spraying of the zinc and the pesticides does not affect the yield of the wheat; in the later growth stage of the wheat, the zinc content of the wheat grains can be significantly increased through the combined spraying of zinc fertilizer and the pesticides; after the combined spraying of the zinc and the pesticides, the molar ratio of phytic acid to the zinc can be significantly reduced, and the effectiveness of the zinc in the grains is improved; under the potential condition of the soil short of the zinc, the combined spraying of the zinc, the pesticides and the biological stimulantsis an efficient agronomic measure that meets the requirements for zinc enrichment of the grains and the control of pests and diseases.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a zinc-enriching method for spraying wheat grains in combination with zinc and pesticides. Background technique [0002] Zinc is an essential trace element for the human body. Insufficient intake of zinc can cause mental decline, growth retardation, impaired immune function, diarrhea and other diseases (Johnson et al.1998; White and Broadley 2005; Gibson2012). It is estimated that about 30% of the world's population faces insufficient zinc intake (Hotz 2001; Gibson et al. 2008; White and Broadley 2011; Gibson 2012), mainly in developing countries and even industrialized countries where cereal crops such as wheat are the staple food Women and children in the country (Hao Yuanfeng et al. 2015). The human body cannot synthesize zinc itself, so it is especially important to get zinc from the diet. About 50% of the residents in China eat wheat and its products as staple food, and a...

AI Technical Summary

Problems solved by technology

However, the enrichment effect of zinc in wheat grains when sprayed with zinc mixed with pesticides and biostimulants is still unclear

In addition, the optimal spraying technique (spraying concentration, time, etc.) for the combined spraying of zinc, pesticides and biostimulants, and the effects of combined spraying on other nutrients in wheat grains need to be clarified
